AMB8626-M Wireless M-Bus Module High Performance 868 MHz SRD Band Key Features Low-cost Wireless M-Bus radio module (868 MHz SRD Band) Embedded Wireless M-Bus according to EN13757-4:2005 standard Small form factor: 17 x 27 x 4 mm Optimized for battery use Easy switching between operating modes S1, S1m, S2, T1, T2, R2 Communication and configuration via UART/SPI Interface Supports AES128 data encryption Conforms with EU R&TTE 1999/5/EC directive Available on Tape & Reel for SMT assembly Also available as wireless USB adapter (AMB8665-M) Compatible to AMB8426-M, enhanced radio chipset radio and 1 microprocessor Description The wireless M-Bus standard EN13757-4:2005 specifies the communication between water, gas, heat and electricity meters and concentrators. The standard comprises various operating modes (S, T and R) to meet the requirements of one-way and two-way data communication in stationary and mobile systems. The AMB8626-M is an all embedded low-cost wireless M-Bus radio module operating in the 868 MHz frequency band. The integrated protocol controls the entire data communication. Data packets are built and transmitted according to wireless M-Bus standard. Configuration of parameters is handled via the UART interface. The module automatically adds the Manufacturer ID and the Address based on parameters configured in the radio module. Measured field strength (RSSI value) offers the option of enhancing quality of the radio link. The customised application layer can be fully integrated in the radio module, thus eliminating the need for an external host microcontroller. The radio module supports the AES-128 encryption standard. A very low-power mode ensures long battery lifetime. The module is pre-certified for operation under the European radio regulations for license-free use. The AMB8426-M is a surface-mount device and is available on Tape &Reel for volume production. Interfaces The AMB8626-M is connected to a host system via an UART interface with data rates of up to 115.2 kbps. Alternatively, a SPI interface is offered (in preparation). When using appropriate firmware, the module is also suitable for autonomously recording digital or analogue signals. Other pins can be used for data flow control and to switch between operating modes. Range of Applications The radio module is designed for automatic meter reading applications for wireless data transmission according to the Wireless M-Bus standard.The radio module is designed to be integrated in meters, concentrators and mobile metering devices. Other applications are conceivable. Its compact dimensions and low-power consumption make the radio module ideal for battery-powered devices. 1 Migration guide avaiable upon request AMB8626-M Dimensions Pin Assignment Pad Name Description ANTENNA Antenna port GND Ground VCC Positive supply voltage UTXD, URXD UART transmit, UART receive SIMO Slave In Master Out (SPI in preparation) SOMI Slave Out Master In (SPI in preparation) SCLK SPI clock (SPI in preparation) /STE Slave Transmit Enable (SPI in preparation) /RESET Reset signal TX IND Signals radio transmission RX IND Signals radio reception MOD SELx wM-Bus mode preselect /RTS, /CTS Hardware handshake /DATA IND Signals incoming data RSVDx Reserved for future use TEST Used for programming purposes Specifications TA = 25C, VCC = 3.3 V if nothing else stated Performance Range* Up to 2000 m RF data rate 2.4 / 16.384 / 66.6 kbps (according to EN 13757-4:2005) Interface data rate Up to 115.2 kbps (UART) Output power 14 dBm (50 ) RF sensitivity Down to -109 / -105 / -101 dBm (50 ) General Power supply voltage 2.0 3.6 V Power consumption - TX: typ. 53 mA - RX: typ. 30 mA - Low Power: typ. 3 A Dimensions 17 x 27 x 4 mm Operating temperature -30 to +85 C Weight Approx. 3 g Antenna External antenna port (50 ) RF technology Frequency range 868.03 - 868.95 MHz Channel spacing 868.03 MHz + k 0.06 MHz k= 0,9 868.30 MHz 868.95 MHz Modulation 2-FSK Conformity Europe EN 300220, EN 301489, EN 60950, EN 50371 * Range stated assumes line-of-sight.
